Short Answer Questions (30-40 words)

Answer:  Author mentions about depletion of ozone layer, melting of ice and retreating of glaciers as indicators. These point out to the global warming. If global warming increases beyond certain point, survival of human kind would become difficult.

 

 

Answer:  Gondwana was a piece of land that existed around Antarctica of this day. Through this piece of land Antarctica was connected to other parts of the world. But later, it was separated into different countries as we see today.

    

 

Answer:  Scientists strongly debate if ice at Antarctica would completely melt. Would Gulf Stream Ocean currents be disturbed? What would happen to human kind in these situations? Also carbon records of millions of years are hidden in ice of Antarctica.

Hence Antarctica is a crucial element.

 

 

Answer: India pushing northwards to form Himalayas. South America moving to join North America. Opening of Drake Passage and commencement of cold circumpolar winds. Antarctica remaining an extremely cold region and at the end of the world.

These could be a combination of mind-boggling activities.

 

 

Answer: Earlier Geoff Green used to ferry celebrities to Antarctica. He noticed that the celebrities were not interested in learning about the continent. So he started the programme for teenagers. They are ready to absorb and learn. They are ready to act as policy makers of future generation. 

 

 

Answer: Antarctica has simple ecosystem. It has lack of biodiversity. Human beings have never lived there. Thus it is a perfect place to understand how even a small change can make big impact on environment.   

 

 

Answer:  The spread of ice to the extent one can see is a breath taking sight. One can readily understand about global warming. It is possible to understand the various geological events that occurred in past and about the importance of clues hidden underneath ice. 

Thus the visit can be a life changing experience.

 

 

Long Answer questions (100-120 words)

Answer: Once a landmass Gondwana existed around Antarctica. Through this Antarctica was connected to rest of the world. But later it goat separated into several countries as we see today. A study of this change can identify various geological activities of past.

A great amount of history can be understood through the carbon records hidden in the ice of Antarctica.

One can observe that glaciers are retreating. Large layers of ice sheets are getting melted. This gives us an indication of present situation of global warming.

Through these studies, one can forecast about depletion of ozone layer and global warming.

Thus study of Antarctica is very useful to us. 

 

 

Answer: Antarctica has a very simple ecosystem. It lacks biodiversity. So it is relatively easier to do environmental studies.

Antarctica is the only place where human beings have not lived. Thus it is easy to understand how even a small change can cause a bigger impact on environment.

Within the sheets of ice, Antarctica holds many million years of old carbon records. These could help us understand the impact of past events on present.

The impact of global warming can be witnessed through retreating glaciers and melting of ice.

Any further reduction in ozone layer may cause adverse impact on phytoplankton. This in turn could impact lives of all animals and birds living in Antarctica.

Owing to above, Antarctica is considered a crucial element in environmental studies.
